Under the My Household, When hitting the “Show on Map” , Google maps comes up, but the “X” in the upper right hand corner does not allow map to be closed. ESC does work, but if you attempt to hit the “X” on the little Google map, you does not work, but allows for the buttons behind it “Teaching” and “Resources” to be chosen.

Also, Help button brings up help page in new window; I suspect this should be brought up in a new tab not new window.

Actually, the problem does happen with Firefox. It's essentially the same issue as was reported in Header appears on top of photo popups. And so it depends on the height of your browser window -- if the height is such that the X in the right corner of the Show on Map popup just happens to be at the same height as the menu in the header ("Scriptures" "Teachings" "Resources" "News") then clicking on the X will activate the menu behind, rather than performing the function of closing the popup.

In the photo case, the menu bled through and was visible, whereas in this case the popup is opaque and you don't see the menu. But clicking in that region still has the same effect.
